The Griffin Armament DUAL-LOK Mount Adapter (1.375x24 - SilencerCo Bravo/HUB) allows suppressors with the common 1.375A-24 HUB/Bravo thread pattern to interface with Griffin's DUAL-LOK muzzle devices. Machined from durable stainless steel, it uses a taper interface, ACME threads, and a locking collar to provide fast attachment, secure lockup, and repeatable suppressor alignment. Designed to expand suppressor compatibility, the adapter lets HUB-pattern suppressors mount to Griffin DUAL-LOK flash hiders and brakes while maintaining a strong, low-shift mounting system.
